UNITED STATES FREDERICK C. ROCKWELL, OF WEST HARTFORD, CONNECTICUT,

FILM FOR THE REPRODUCTION OF PICTURES.

Application filed January 22, 1920v To all QUJLOHI, it may concern:

Be it lrnown that T, FREDERICK 0. Room warm, a citizen oi the United States, and a resident oi lVest Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved. Film For the Reproduction of Pictures, of which the following is a specification.

My invention relates to the class of articles above named, the im ention being particularly susceptible of use in a photographic film such as is used in a moving picture camera. and an object of my invention among others, is to provide a film by means of which new and striking effects may be produced in pictures resulting from exposure of the films.

A film embodying my invention and in the construction and use of which the ob jects herein set out, as well as others may be attained, illustrated in the accompanying drawings, in which Figure l is a plan view or a section of. film embodying my invention.

Figure a view in section through the ,-1an:c on plane denoted by dotted line 2--2 ol' i ig urc l, the thickness oi the film being exagz' 'eratcd in order to clearly illiiistrate the in vention.

My invrmtion is not limited to any particular lrind of film or other device employed to o hplay pictures, but as it is especially adapted for use in connection with films commonly used in movim picture cameras, such a film has been selected by me for illustratinn my invention in the drawings herein.

A film or other device, to embody my invention, will be composed. olt' transparent 1naterial, devoid of shaded areas. Such film is simply embossed in whole or in part, may be desired, on the picture section thereof, the embossed parts being formed preferably on curves and without angles the elevated ised portions thus fcrmcd concentrating and diaper-sing: the li t rays, there by priulucing lighted areas of different degrees o'l intensity. film thus formed will cause the proi'luction of a 'iicture having rtain portions with extremely iigh lights and other portions having: lights of lesser degrees o'l intensity. The parts of the film formed in relief on one side will, oi course, occur as depressions or in int-aclio on the opposite side of the film. It Ly purpose to form these relief of different heights in order to vary the deg cc of intensity oi the lights in Serial No. 353,364.

different portions oi therefrom and of depths of the ii ried accordingly.

This dea a film with embossed surfaces ill s..i.'atcd in the accompanying drawings in which the numeral 53 indicates a film particularly adapted for use in movin picture cameras, and that may be of any ed transparent n'iaterial, such film havthe usual p 'orations 3 by means of rich it ted. The highest or alto-relievo portions 7 on one side of the picture section of the film denote petals of a conventional form of flower, the next highest or mezzorelieve port ons 8 on said picture section repenting u leaf on the vine of said flower, 1nd the still lou'e" or has-relief portions 9 on Ron representing the vine the pictures produced course, the corresponding 'lioed surfaces will be vapicture sect lf as a result of this formation when one side of the film is exposed for proiection purposes the alto-reliero portions will produce the higher lighted parts of the picture the IllULfiLiO-llllltl(0 portions the areas having the decree o1" l tensity, and the basreliel" portions at c, o ight of still lesser degrees i picture may be exposed s usity. The the side opposite to that above men- ,EOPAVi acing the project-inn medium, and l0 cilia-ct will be not only a reversal of the stature but a surprising hange in the lighted areas of the picture itself, owing to the different degrees of intensity of the light in difi erent portions. Those parts of the film that before produced the higher lighted in the pi ure now producing the areas hating lesser V hts, and vice versa.

My invention, therefore, not only contemplates an embossed but a reversible film, that is, a film that may be exposed with either side to the projecting medium and each side thus exoosed will present a picture of en tirely (ll lei-enteffects from that produced by an exposure in the o posste side. thus in. ef- :t'ect producing with the same film two pictures distinctiivelx diflerent in appearance.

is [y improved embossed film with the aised and depressed portions to bring; out he high and lesser lights will be fouhd to n'oduce a picture in which the stereoscopic llects are particularly enhanced. such picure having rli'llerent decrees of depth there- 'n bro'in'ht out to marked degree by the rob Jsed feature of the film. I

M impr red film is particularly susceptible to the coloring process, by means of which the pictorial efi'ects will be greatly enhanced and such coloring may be applied in a very simple, inexpensive and effective manner.

A color applying implement being passed across such film a certain color will be imparted t the higher portions thereof, and the film being reversed another and different color may be applied to the higher portions ct its opposite side, these being the lower portions of that side of the film first treated with color. It will .thus be seen that different colors may be readily and quickly applied to the film, resulting in the production of a colored picture having striking and pleasing etlects. y

In another manner of applying the color the film may be partially embossed and the raised portions thereof, of the lower order, will have the color applied as herein above described to suchportions. A succeeding step in the embossing operation may now take place and embossed portions of a greater degree of elevation may be produced to which the colors may be applied, and this process may be continued thereby enabling color in endless variety to be readily applied to the picture. No special color supplied to any of the raised or depressed portions is contemplatedherein, as such colors may be applied in any manner to suit the tancy ot the artist.

It will, oi? course, be understood that the raised and depressed portions of the film will be very minute, the drawings representing to an exaggerated extent the embossing, this in order to thoroughly bring out the invention. The embossing may be accomplished in many different ways, as by hand, by a molding process, by a photo graphic process, or by other means, and I do not limit my invention to any special means of embossing the films.

My improved film providesmeans whereby the lower lights sometimes employed in silhouettes may be produced in a manner to bring out surprising results as to such lighted portions.

I claim:

1.. An embossed film for the reproduction of pictures said embossing being located on the picture section of the film.

2. A film for the reproduction of pictures comprising raised portions on one side of the picture section of the film and corresponding depressions on the opposite side of section.

3. A film for the reproduction of pictures comprising embossed portions on one side raised to different degrees from the plane oi 'the film.

4s. A film for the reproduction of pictures comprising embossed portions raised to different degrees on one side and corresponding depressions of different degrees of depth on the opposite side.

5. A film for the reproduction of pictures comprising raised portions on one side thereof having color applied thereto,

6. A film for the reproduction of pictures comprising raised portions on one side with color applied thereto, and correspopding depressions on the opposite side with a different color applied thereto.

T. A film for the reproduction of pictures comprising a transparent body embossed to provldeblunt prqected'portions on the face ot the film tor the production of light therethrough.
